I fabricated the attached jig for installing or removing Skybolt Grommets. The grommets have to be installed to get the fasteners and receptacles positioned. That has to be done first to get the split line perfect. Problem is the grommets fit really tight. Too tight to push into place with bare hands. Press fit tight. Later they have to be removed to paint then reinstalled. Lots of opportunities to scratch that beautiful paint.
The jig is simple, but it works great and no scratching of the paint when they get final installed. It's just a 5/16" bolt, washer, nut, 1/2" bushing and a chunk of PVC pipe. The business part is the 1/2" bushing. One end is ground down the 15/32". Thats the dimension of the grommet on the inside of the cowl. The other end is left 1/2". That's to drive the outer end of the grommet. The 1/4" thick slice of PVC is a spacer is bored to 5/8" to allow the grommet to be pulled in or out. Photo explains it pretty well. It's set up to push the grommet back out. Yes, it's ugly but it works. YMMV.
